Abstract: A system for drying first and second enclosures includes first and second drying units, each drying unit including a process air stream moving through a process chamber, a reactivation air stream moving through a reactivation chamber and a rotating desiccant wheel configured such that a process wheel portion is located such that the process air stream moves therethrough, and such that a reactivation wheel portion is located such that the reactivation air stream moves therethrough. The reactivation air stream passes through a heating coil before passing through the reactivation wheel. A liquid heating unit circulates first and second heated liquid flows through the heating coils of the corresponding first and second drying units located respectively to dry the first and second enclosures. A flow control is operative to adjust a volume of the first and second heated liquid flows.

Abstract: A heat exchanger apparatus for a portable tank that has an access opening and an access door removably attachable to seal the access opening. The apparatus includes a cover plate configured to be removably attached to the access opening to seal the access opening, and a heating circuit attached to an inner surface of the cover plate such that when the cover plate is attached to the access opening, the heating circuit extends into an interior of the tank. Input and output ports extend through the cover plate and are connected at inner ends thereof to the heating circuit such that fluid flowing into the input port flows through the heating circuit to the output port. The input and output ports are adapted at outer ends thereof for attachment to a fluid heating system to circulate heating fluid through the heating circuit.

Abstract: An apparatus and method for enhancing the transfer of heat in a fluid within a reservoir. The interposition of heat exchangers between a primary heating arrangement and an auxiliary heating arrangement results in greater utilization efficiency in heat transfer to the fluid within the container. A predetermined arrangement of heat exchangers within the reservoir containing the same is also disclosed.
